NewsNew agent inhibits Staphylococcus aureus toxin – hope for pneumonia patients
Researchers have developed a miniaturized test system that allowed them to screen over 180,000 compounds for their ability to block the effect of the key virulence factor α-hemolysin in S aureus. Drug candidates from the quinoxalinedione class, in particular the compound H052, proved to be highly effective, both in cell culture and in animal models.

NewsPurified immunoglobulin F(ab′) 2 prevents lethal staphylococcal enterotoxin B intoxication in mice and rhesus monkeys
Purified F(ab′)2 fragments are an effective antidote to lethal SEB doses in mice and rhesus monkeys, and therefore might be a favorable candidate for treating patients with severe SEB intoxication, a new study suggests.

NewsThroat microbiome holds clues to older Australians’ health
A simple swab from the back of the throat, known as the oropharynx, may offer clues about health challenges faced by aged care residents.

NewsReactive nitrogen species dominance is key in the fight against antimicrobial resistance
The balance between two types of molecules – reactive nitrogen species (RNS) and reactive oxygen species (ROS) – plays a crucial role in tackling drug-resistant bacteria, according to a new study.

NewsResearchers uncover how Staphylococcus aureus ‘steals’ iron from our blood during infections
Researchers have revealed how Staphylococcus aureus bacteria extract iron from hemoglobin – a process crucial to their survival during infections. The study has identified the full sequence of protein–protein interactions during this iron ‘theft’.

NewsVentilation fans can significantly lower the risk of inhaling bacteria particles after toilet flushing
New research finds that unhealthy concentrations of bacteria are released into the air by toilet flushing - but active ventilation with an exhaust fan reduce the risk by 10 times.

NewsDangerous bacteria lurk in hospital sink drains, despite rigorous cleaning
Even in modern hospitals, drains can serve as reservoirs for known and novel pathogens, according to a new study.

NewsDiabetes can drive the evolution of antibiotic resistance, study reveals
A new study shows that people with diabetes are more likely to develop antibiotic-resistant strains of Staph. The results show how the diabetic microbial environment produces resistant mutations, while hinting at ways antibiotic resistance can be combatted in this patient population.

NewsTurmeric teamed with light can help ward off superbugs
In a new study, researchers have evaluated a low-cost yet effective technology called photodynamic inactivation using curcumin to curb bacterial resistance.

NewsWhy some kids get sicker: The hidden power of nose bacteria
A scoping review unravels how bacterial colonization in the respiratory tract impacts both the severity of respiratory syncytial virus (RSV) infections and long-term respiratory health in children.

NewsDelicate nanoflower is deadly to bacteria
A carnation-like nanostructure could someday be used in bandages to promote wound healing. Researchers report that laboratory tests of their nanoflower-coated dressings demonstrate antibiotic, anti-inflammatory and biocompatible properties.

NewsCARB-X funds Rhode Island Hospital to assess feasibility of direct from blood detection of bacterial pneumonia
Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) will award Rhode Island Hospital at Brown University Health US$1M to demonstrate proof-of-concept of a polymerase chain reaction (PCR) approach informed by RNA sequencing to detect bacterial pneumonia directly from whole blood.

NewsSophisticated early warning system: How bacteria respond to threats
Recent research has found that exogenous petidoglycan fragments of Vibrio cholerae and other multidrug-resistant pathogens are able to trigger 3D biofilm formation as an universial danger response.

News$7 Million grant to tackle lung infections through innovative probiotic treatment
The PROTECT project seeks to combat lung infections by assembling a community of beneficial lung microbes that can outcompete harmful pathogens.
-
NewsScientists can pinpoint bacterial needle in haystack using fluorescence
Bacterial troublemakers are able to survive antibiotics and are not detected by diagnostic antibiotic resistance testing. A new method has been developed to look at single bacteria and to find the antibacterial resistant ones, or the troublemakers, among them.

NewsResearchers to study how much MRSA is lurking in the air in hospitals
Scientists are working to minimize health care workers’ exposure to MRSA, or methicillin-resistant Staphylococcus aureus, a type of staph bacteria that’s become resistant to many of the antibiotics used to treat ordinary staph infections.
